A washing machine is supposed to clean your clothes, not leave them smelling worse than before. Yet this is one of the most common problems in South African homes. If your washing machine smells bad, produces a musty odour, or leaves clothes with an unpleasant smell after washing, it is a clear sign that something inside the machine is not functioning as it should.
In many cases, this issue develops gradually. What starts as a mild odour can quickly turn into a persistent smell that affects every wash cycle. The good news is that most causes are identifiable and can be resolved with the right cleaning approach or professional intervention. If the smell continues despite cleaning, it may be time to consider washing machine repair services near you to address underlying faults.
This issue affects most major washing machine brands, as all units rely on similar internal systems such as drainage, seals, and detergent distribution. Whether you own a premium or standard unit, components can wear over time if not maintained correctly. At Glotech Appliance, we regularly repair leading brands including Samsung washing machine repairs, LG washing machine repairs, Bosch washing machine repairs, Defy washing machine repairs, and Miele washing machine repairs, ensuring the correct parts and repair methods are used for long-term performance.
This guide explains the real causes behind washing machine odours, how to clean your machine effectively, and when to call a technician.
Why Washing Machines Develop Bad Smells
Washing machines operate in a warm, damp environment, which makes them the perfect breeding ground for bacteria, mold, and detergent residue buildup. Over time, these elements accumulate in hidden areas such as the drum, seals, pipes, and detergent drawer.
In South African conditions, factors such as humidity, water quality, and frequent use accelerate this process. Front loader washing machines are especially prone to this issue due to their sealed design, which traps moisture.
Common Causes of Washing Machine Smells
Mold and Mildew Build-Up
One of the most common causes of a bad-smelling washing machine is mold growth. Mold thrives in damp environments, particularly around the rubber door seal in front loaders.
Signs include:
• Musty smell
• Black or dark spots on the rubber seal
• Odour worsening over time
Detergent and Fabric Softener Residue
Using too much detergent or low-quality products can leave residue inside the machine. Over time, this buildup creates a sticky environment where bacteria thrive.
Common indicators:
• Slimy buildup in detergent drawer
• Residue inside drum
• Clothes not smelling fresh after washing
Blocked Drain Pump or Filter
Debris such as lint, coins, and dirt can accumulate in the drain system, leading to stagnant water and bad odours. If your machine is also showing drainage issues, this may be linked to a deeper fault:

Dirty or Clogged Hoses
The inlet and drain hoses can trap residue and bacteria over time. This is often overlooked during routine cleaning.
Low Temperature Washing Habits
Washing primarily on cold cycles may save energy, but it does not effectively kill bacteria. Over time, this leads to buildup and odours.
Standing Water Inside the Machine
Water that remains in the drum, pipes, or pump after a cycle can quickly develop a foul smell.
How to Clean a Smelly Washing Machine
Cleaning your washing machine properly requires more than just running an empty cycle. A targeted approach ensures all affected areas are treated.
Step 1: Clean the Door Seal
The rubber seal is a major source of odours.
What to do:
• Wipe inside the seal with a cloth
• Use a mild cleaning solution
• Remove visible mold and residue
Step 2: Clean the Detergent Drawer
Remove the drawer and wash it thoroughly.
• Rinse with warm water
• Scrub away residue buildup
• Dry before reinserting
Step 3: Run a Hot Cleaning Cycle
Run an empty cycle on the hottest setting.
• Add a washing machine cleaner or vinegar
• Avoid adding clothes
• Allow full cycle to complete
Step 4: Clean the Drain Filter
The drain filter often collects debris that causes smells.
• Locate the filter (usually bottom front)
• Remove and clean thoroughly
• Check for trapped objects
Step 5: Inspect and Clean Hoses
• Disconnect hoses if accessible
• Flush with clean water
• Check for blockages
Step 6: Leave the Door Open
After cleaning, leave the door slightly open to allow airflow and prevent moisture buildup.
Preventing Washing Machine Odours
Preventative maintenance is key to keeping your washing machine fresh.
• Use the correct amount of detergent
• Avoid overloading the machine
• Run a hot cycle regularly
• Clean seals and drawers weekly
• Leave the door open after use
When a Bad Smell Indicates a Bigger Problem
Sometimes, a persistent smell is not just a cleaning issue. It may point to internal faults.
Possible underlying issues:
• Failing drain pump
• Blocked internal pipes
• Worn seals allowing buildup
• Electrical issues affecting cycle performance
If your machine also shows symptoms like leaks, poor drainage, or unusual noises, you may need professional repair:
👉 washing machine leaking
👉washer pump replacement
Impact of South African Conditions
Local factors contribute significantly to washing machine odours:
• Humid coastal environments like Cape Town
• Hard water in certain regions
• Frequent washing cycles in busy households
• Load shedding disrupting cycles
These conditions accelerate residue buildup and bacterial growth, making regular maintenance even more important.
When to Call a Professional Technician
You should consider booking a technician if:
• The smell persists after thorough cleaning
• The machine is not draining properly
• You notice leaks or water buildup
• The odour returns quickly after cleaning
• There are unusual noises during operation
Book a professional washing machine repair service near you to identify hidden issues and ensure long-term solutions.
